  1. Trace fossil?

    I found this in our property southeast Oklahoma. The area is Pennsylvanian in age. My first thought was that it may be weathered barite (Rose Rock) which is the state rock. However, they are Permian in age and not found in this area to my knowledge. Now I’m thinking either weathered chrinoid (calyx?) maybe a cluster of burrows, or just a really cool looking rock. Any help would be appreciated. The item is 4” x 5.5” in size.
  2. Oklahoma Trilobite

    This trilobite is labelled as Viaphacops from the Bois D'Arc Fm., Devonian, Oklahoma. Can anyone confirm and perhaps assign a specific epithet? Scale in mm.
  3. Chouteau OK

    Found this piece just east of Chouteau, OK the area is right on the boundary of Pennsylvanian and Mississippian era rocks but I suspect this plate is Pennsylvanian. There are some pretty cool chrinoid pieces in the plate but I am specifically trying to identify the piece that looks like a piece of barbed wires in the middle of the piece. Archimedes?
  4. Eastern Oklahoma

    Found this imbedded in a rock and we’re trying to ID it. It looked to us like the back of a crab. It’s approx. 7 cm across. Found in NE Oklahoma, near Tahlequah, high on hillside. Does that make it Devonian period at the latest? Please assist.
  5. 3D Jellyfish sharing

    Merry Christmas folks. Just wanted to share some photos of one of my favorite specimens.. It's a 3D mold of a Scyphozoa conostichus jellyfish from the Pennsylvanian period from the Nellie Bly Formation, Sand springs, Tulsa, Oklahoma. It's 5.3 x 4.5 x 4.0cm.
  6. Hello, I recently found these three items in Custer County Oklahoma where Quaternary mixed with Permian and Cretaceous bedrock can be found. They were all found about 5 feet from each other with items one and two on top of each other. When I hold them they remind me of a terracotta pot in texture and kind of sound like terracotta when you tap on them. I am guessing they are fossilized bone? If it is bone I would love to figure out what it came from but understand that determining exactly what it was from may be difficult. I appreciate any input on what they could be and would also understand if its too difficult to determine. Below is item one, kind of flat.. Maybe a Skull?
  7. For your viewing pleasure. Sharing with the group.
  8. Crinoidal Holdfast?

    Here is a picture of what I believe to be a crinoidal holfast on a brachiopod shell. This is very small (scale on the side are mm's) but I thought it was pretty neat looking. I found this while cleaning some of my material I collected earlier this year from the Haragan Formation (Lower Devonian) near Clarita, Oklahoma. When I first saw it, I thought: "this looks like a little starfish", then I learned to count! So I am assuming this a a holdfast, but I am wondering if anyone can : 1) confirm that; 2) provide any more precise ID; 3) point me to any references that might help. I have gone through Oklahoma Geological Survey Circular 55 on crinoids, but did not see anything like it (it doesn't have much on holdfasts, no surprise). Thanks for any help anyone can offer.
  9. A couple weeks ago I met with a retired paleontologist that specializes in Pennsylvanian cephalopods. I showed him all my finds from a certain site here in NE Oklahoma and he was kind of surprised with what I had found (and wasn’t finding). There were a couple common goniatites and nautiloids, a few uncommon ones and five specimens of one type of goniatite he didn’t recognize. He checked his book and still couldn’t match a suture pattern and told me it may be an undescribed species. He noted down the pattern and said he was going to double check, but if it ends up being the case, he would potentially try and get it written up. So, my question is, for those of you who have been through this before or do it for a living, what all does describing a new species entail?
  10. possible snake fossil?

    Just joined today so first time posting! *I can already tell this is going to be my new favorite site! I originally found this fossil when I was about 11 years old. It was found on a rock cliff in the middle of Lake Eufaula in Eastern Oklahoma. I begged my uncle to take me to the rock cliffs projecting from the center of the lake so I could throw rocks in the water. I remember the cliff being very tall and all a light grey color. the rocks flaked apart really easy so I was having a hay day chipping off big flecks and tossing them down to the water below. to my surprise I flaked off this piece and decided it was too cool to toss in the water. I tried to follow the shape both directions but my uncle got impatient so I didn't get to find the head or tail. I rediscovered this piece at my Dads house in the attic about 8 years ago . I had forgotten about it so it was like discovering it all over again. I am 35 now and am truly amazed I still have it considering all of the moves I have been through. My wife and I are finding ourselves with more time to go on adventures so we are thinking about getting into hunting. thought if I could get some inside into what exactly I found may help reignite my passion for exploring the unknown.(unknown to me anyway) Thanks in advance for your time. Shane - Okc, OK
  11. Love to know what this is?

    We found this while cutting trails in our forest, on the banks of our spring fed natural pond. We live in southeast Oklahoma, in the Ouachita National Forest, in the Kiamichi River Valley. All of which used to be underwater eons ago. Every single person who has seen it in person, has said it looks like a petrified turtle. It’s heavy like stone & the top is darker with a slight greenish tint & is very smooth & not rough like the bottom or like a rock. The outdoor lighter is 12 inches long. Thank you so much in advance, for your help & insights into what it could possibly be!
  12. Fossil Sites in Oklahoma

    Hey guys, I was wondering if any of you know where some fossil sites are in the state of Oklahoma. I am a noobie in the field of paleontology but I want to learn more and want to go on trips to quarries and places where fossils are located. I know relatively what is located in Oklahoma: trilobites, bryozoans, echinoderms(crinoids), blastoids, brachiopods, etc. Me and my friend Ian are interested in going to different locations such as the Thesien Quarry or White Mound. Me and him have never been on this type of trip before but I'm eager to visit one of these sites. I was also wondering if you guys had any advice for me or just some helpful information to due with searching or picking specific sites. Thanks.
  13. Trilobite tail, or not?

    I found this Cryptolithus in the Late Ordovician, Viola Springs Formation of Carter County Oklahoma. Can someone tell me if it is C.fittsi which I see on a fauna list for the site or another species? I'm also wondering if the segmented strand below it is part of the tail or something else?
  14. Hello, I recently acquired my first trilobite from Oklahoma and am looking to confirm.... do these specimens typically show a soft orange color under a black light? I have every reason to believe that the specimen is 100% genuine but I was slightly surprised to see that the piece gives off a faint but even orange color under closely applied black light across 95+% of the fossil. There are a few spots that give off no glow/color and these appear slightly darker to the eye under normal light. The matrix obviously gives off no color whatsoever under black light. As I said, the seller (which I won’t name here per forum guidelines) is very reputable so I have no reason to doubt that the piece is original/genuine, but just looking to confirm that the faint orange glow is normal as I wasn’t entirely expecting it. I was told that no restoration/color/painting was done to the specimen. Thank you for any thoughts!

  17. Greetings fellow fossil lovers! Below is an assortment of fossils from the Waurika clay from the Lower Permian that I'm having trouble placing an id on. Scale bar is in millimeters. Any help would be greatly appreciated. Thanks All! Jacob
  18. Amateur hunter needs help!

    Very much an amateur here. Recently some farmland in east Tulsa was scraped off for a new housing addition. I have found lots of crinoid stems and a few shells and trilobites. But I don’t know what this is that I found today. Can anyone help?
  19. Can anyone ID this fossil?

    Found this while hiking turkey mountain urban wilderness area in Tulsa, Oklahoma, USA. It was found next to the path among other rocks (mostly sandstone) above the Arkansas River.
  20. 3 Day Trip with my girl

    Hi Folks, I am planning out my first long road trip to collect with my youngest daughter for next week.(she's 13 and we have our local Pennsylvanian rocks we collected together for years, but I have been overseas working for a year, and I am getting ready to go back to do one more year, and I want to do something fun with her and she asked to go look at rocks and collect since she knows it's my favorite thing I never get to do) Anyway, I've been out of country until about 2 weeks ago, and I know there's been a ton of rain in Oklahoma, and I am curious if I should try to head to Mineral Wells and Jacksboro in Texas, and maybe head back towards Arkansas, or should I head north to Kansas and maybe cross over into Missouri. I'm at a loss since I don't get much US news in Vietnam, so I have no idea what everyone's weather has been like, and I'm not looking for honey hole suggestions, just a few places I can take her that she can find stuff and we can just have some time together. Pay sites are okay too if you have some suggestions. Thanks, Jim
  21. Echinoderm??

    I have found 2 invertebrate fossils that I haven't found before. They appear to be five-sided and one shows a star fish pattern on the top. The bottoms are curved and smooth. The dimensions are about 0.5 cm in diameter and 1 to 2 mm in thickness. Any help in identifying would be greatly appreciated as usual. (The rocks from the lake are from the Pennsylvanian period). Are they a type of echinoderm? The shape and characteristics of the underside seem a bit odd-could it be a central part of an echinoderm? Another question that comes to mind is why are they so similar yet one lacks the five radial lines visible on the other?
  22. These beauts are an extinct fossilized button coral, Gymnophyllum wardi. The article mentioned that they are from the Pennsylvanian part of the Carboniferous period. I found these along the shoreline of Okmulgee lake in Okmulgee, Oklahoma. Apparently G. wardi is the only species found in the genus Gymnophyllum and may only be exclusively found at Okmulgee Lake or neighboring Dripping Springs lake although I'm not positive on that. The ones below are about 10 to 15 mm. One thing that I found interesting is that the waves from the lake constantly expose more of these fossils over time perhaps bring more in from the lake bottom. They are very lightweight. I recall not finding these along a section of shoreline where another person had been collecting them only to come back the next day and finding several in the same area! That is pretty exciting! Comments welcome as always.
  23. I obtained a bone fossil collected from the Arkansas River in Eastern Oklahoma but not sure what it belongs to. I am including several photos from various angles. The dimensions are as follows in centimeters(cm): 16.5 cm x 9 cm (about 0.64 cm in thickness but it varies slightly). The darker brown sections appear to be the outside of the fossil while some parts are interior(?); not sure about the black portions. Any help on what it might belong to and perhaps what part of the structure would be awesome!
